Accessing Ollama running on host OS from inside Docker-in-docker container in VM

If you run Ollama on your host OS, but want to access it from within a protected container:

1. Install Colima and Docker-in-Docker (link)
2. Install Ollama on host (link)
3. Access Ollama from the container with URL: http://host.docker.internal:11434

Installing Ollama and OpenWebUI on Ubuntu 24.04

Notes

• you should first add your user to the following Unix groups: video, render, docker, ollama

  • sudo usermod -a -G render,video $LOGNAME

• make sure user ollama is added to groups video and `render

• install Docker (ideally in a dedicated VM; see https://gist.github.com/peterwwillis/e2b37e5dd502fd7ffc3833f56feade1e)

Installing and running Docker-in-Docker in a dedicated Colima VM, for AI agent work

You may want to run an AI agent in a "safe" environment, but with ease of use. The closest thing is a VM running Docker. You get the tooling and ecosystem of Docker, with the safety of a VM that you can delete (when the agent goes crazy, breaks out of the VM, steals your wallet and runs off with your wife (I miss you, Elaine...))

Colima is perfect for this, as it creates the VM and sets up Docker. It even keeps persistent files in a different volume than the VM's root disk, so you can just delete and recreate the root disk and your files are still there.

You can have multiple Docker contexts, one for "safe" work (in one VM), and one for "dangerous" AI work (different VM).

The only real downside to Docker is a VM volume filling up with container images.

Setting up ThinkPad T14s Gen4 for Ubuntu Linux 24.04

About

I finally settled on a new personal Linux laptop, and it's the Lenovo ThinkPad T14s Gen 4 w/AMD processor, 32GB RAM, and Low-power 500 nits display.

I had mine shipped with Ubuntu, it comes with (I think) Ubuntu 22.04.01 LTS. It's nice because they set up the BIOS to come with Secure Boot enabled for Ubuntu. Everything works out of the box.
